epoch to show millseconds

Hi All
I've searched the archives, but it seems that there's no mention of this.
Basically, what I want to do is to show the milliseconds value.
When I do a:sample=# select date_part('epoch', current_timestamp); date_part----------- 994832815
how do I make it accurate up to milliseconds value? the above is only up to
seconds.This is on Postgresql-7.0.3, btw.Thanks!



cheers
